Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a method for the comprehensive utilization of organic selenium-enriched rice cultivation and selenium-enriched rice by-products: (1) by adopting selenium-enriched seedling-raising substrate to raise seedlings when rice seedlings are raised, germination and raising seedlings from rice From the beginning, rice has been provided with sufficient selenium sources, so that rice can absorb from the soil throughout the growth period and convert it into organic selenium through photosynthesis, so that the organic selenium content in rice is high and stable; seedlings are raised with selenium-rich seedling matrix and the method of soil fertilization, cultivate organic selenium-enriched rice, change the drawbacks of foliar fertilization to produce selenium-enriched rice, reduce the application of inorganic selenium fertilizer, reduce the pollution of selenium fertilizer to the environment, and reduce production costs, solve the problem of existing fertilization In the method, the content of selenium fertilizer is relatively high, which increases the cost of using fertilizer, and is easy to cause certain pollution to field runoff water and soil, and causes large residual amounts of inorganic selenium, and the problem of low safety; (2) by using fertilizer mixed to produce The granulation equipment produces organic selenium-enriched special fertilizers. The two agitators are continuously rotated by driving the motor, and the raw materials of the organic selenium-enriched special fertilizers are put into the inner cavity of the mixing chamber from the two feed ports, and the rotating agitation The machine stirs and mixes the raw materials of the organic selenium-enriched special fertilizer. After mixing evenly, the raw materials of the organic selenium-enriched special fertilizer enter the inner cavity of the conveying pipeline through the discharge pipe and the receiving pipe, and the running of the conveying motor drives the threaded conveying rod to rotate. The raw materials of the organic selenium-enriched special fertilizer are conveyed forward, and the raw materials of the organic selenium-enriched special fertilizer are transported from the material connection port to the inner cavity of the storage box through the discharge pipe, and the raw materials of the organic selenium-enriched special fertilizer are further Stirring, the raw materials of organic selenium-enriched special fertilizer move with the granulation roller, the granulation roller squeezes the raw material of organic selenium-enriched special fertilizer, and the raw material of organic selenium-enriched special fertilizer passes through the extrusion hole of the granulation sleeve Extruded to form granules, which are discharged through the fertilizer output pipeline to obtain the special organic selenium-enriched fertilizer, which solves the problem that the existing selenium-enriched fertilizer has low mixing uniformity, low quality, and different shapes and sizes. The problem of different quality of selenium-enriched products

Abstract

The invention discloses an organic selenium-rich rice cultivation and selenium-rich rice byproduct comprehensive utilization method. In the organic selenium-rich rice cultivation method, a selenium-rich seedling culture medium is adopted for seedling culture during rice seedling culture, and sufficient selenium sources are provided for rice, so that the content of organic selenium in the rice is high and stable; according to the cultivation method, application of inorganic selenium fertilizer is reduced, pollution of the selenium fertilizer to the environment is reduced, the production cost isreduced, the organic selenium-rich special fertilizer is applied to the soil, the stress resistance of crops is improved, photosynthesis is improved, root system development is stimulated, crop growth and selenium absorption and conversion are promoted, and therefore the purposes of saving fertilizer, reducing cost and improving rice quality are achieved. According to the comprehensive utilization method of the organic selenium-rich rice by-products, the by-products of the organic selenium-rich rice are used for producing selenium-rich potatoes, selenium-rich fruits and selenium-rich eggs, waste is turned into wealth, use of fertilizer and feed is reduced, the production cost is reduced, and meanwhile the selenium content of other products is increased.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for organic selenium-enriched rice cultivation and comprehensive utilization of selenium-enriched rice by-products. Background technique [0002] Selenium is an essential trace element for humans and animals. It is an antioxidant that can relieve aging and eliminate a variety of harmful free radicals. Its synergistic effect with vitamin E is called the "golden partner" of anti-oxidation. Selenium deficiency will lead to the decline of human immunity. Severe selenium deficiency will cause various diseases such as coronary heart disease, hemolytic anemia and liver cancer. Although there are many ways to supplement selenium, it is generally believed that the selenium of the human body mainly comes from food. Food selenium supplementation is more suitable. Compared with inorganic selenium, bio-sourced organic selenium has the advantages of high absorption and utilization...
